Skylight / July 14, 2018 / Onfroi Berger
Your ventilating skylight can be operated by one of three ways: Manual skylight controls - These are opened by your use of an extended rod to manually crank the skylight open. These are designed for ceilings of less than 15 feet. Electronic skylight controls - A simpler model of this type of control is wired to a wall mounted switch which opens and closes the skylight. More complex models are controlled by a special wall console of a wireless remote control. Automatic operating controls - With this type of control integrated heat sensors trigger the skylight to open when the interior heat reaches a preset temperature. Exterior sensors automatically close the unit when they sense moisture.
The acrylic dome is typically mounted in an aluminum frame which is in turn mounted on a box called a "curb." Once the hole is cut in the roof to the manufacturers specifications the curb is typically constructed on-site to raise the skylight above the level of the roof sheathing. Site-built or factory-supplied flashings are used to seal the roofing around the curb. Domed skylights are available in clear smoked bronze or other tints. Some domed plastic skylights are flush mounted which means that the lens piece and flashing piece are both made of plastic and then placed on the roof without a curb. The problem with this type is that they are loud and very susceptible to leakage.
Typically flat glass skylights include all the installation materials and they are among the easiest to install. Moreover because they are glass these flat skylights are less likely to scratch. Domed acrylic skylights are among the most affordable especially compared to glass alternatives. These skylights are available in a variety of tints making them an attractive addition to any home or room. Unfortunately domed acrylic skylights do not offer the same noise protection as glass varieties and they tend to be more susceptible to leaking. Function Now that you know a little bit about the types of skylights available you should take some time to consider their function.
